Abstract A coupled Earth’s thermosohere-ionosphere global dynamics model (for altitudes of 90–500 km) is presented. This model is based on a three-dimensional thermospheric general circulation model and a dynamical model of the ionospheric F-layer, which takes into account plasma-chemical processes, ambipolar diffusion, and advective ion transport due to neutral wind. General upper atmosphere characteristics have adequately been reproduced and the thermosphere–ionosphere interaction has quantitatively been estimated based on this coupled model. The sensitivity of thermospheric characteristics to ionospheric parameters and the sensitivity of the electron-concentration field distribution in the ionospheric F-layer to thermospheric parameters have been studied within a specified diurnal cycle.

耦合地球的热源-电离层全球动力学模型

摘要 提出了一个耦合的地球热相-电离层全球动力学模型（高度为 90-500 公里）。该模型基于三维热层大气环流模型和电离层 F 层动力学模型，其中考虑了等离子体化学过程、双极扩散和中性风引起的对流离子输运。一般的高层大气特征已被充分再现，并且热层-电离层相互作用已基于该耦合模型进行定量估计。研究了热层特性对电离层参数的敏感性和电离层 F 层中电子浓度场分布对热层参数的敏感性在指定的昼夜循环内。
